The object is in the center of the slicer table, but when I export the g-code and upload and print the object prints of-center by about 80mm. I tried more than one slicer with the same result.

The motors started to work properly with a value of T5

What is the max T values you suggest to be safe?

@jddt Changed to 128 Micro Steps

Thanks for noticing the error in my calculation. I am using external drivers and are not using the M350 command.

Settings I am using now. Can the T setting influence the accuracy of my steps?

I am using external drivers. All my final drive pulleys are HTD5 20 tooth. I do not get any consistency with the distance the axis move.

See calculations below.

When I completed the steps/mm calibration and I run code, like the homing code, then the distance is completely wrong.

Any advice.
Thanks

Does the M906 command to set the motor current work for external motors as well?
